Title: Prodn of coke by the two stage removal of volatiles - from coal with air efficient combustion in the first stage
Inventor: MANSFIELD VAUGHN
IPC: C10B49/04
Filed: 1968-10-25
Abstract: Production of coke of high fixed carbon and low volatiles content from coal in a chain grate process by (1) igniting the coal under air starvation conditions, suitably on a horizontal chain grate and pref. under conditions such that the ignited product fed to the next stage has a temperature of 1400 to 1600 degrees F and a 7 to 10% volatile content, (2) discharging the product from (1) into a vertical coke cooler, (3) feeding inert gas into the bottom of the cooler, thereby generating a zone of burning volatiles in the cooler through which the product from (1) must fall and (4) removing the cooled coke from the bottom of the cooler. The lowering of the combustion temp. on the chain grate gives a longer operating life, and the maintenance of the zone of burning volatiles in the cooler ensures that the volatile content of the coke is low without deleteriously affecting the fixed carbon content, giving an overall thermal improvement over conventional operation.
